In many such fanfictions, when Naruto gets his inheritance, he often gains new and powerful abilities. For example, he might inherit some unique jutsu from his ancestors. This could make him even stronger than he already was in the original series, allowing him to face tougher opponents with ease.
In 'Harry Gets His Inheritance' fanfic, Harry may get some really cool magical items as part of his inheritance. Maybe a wand that has special powers or a cloak that has enhanced invisibility. His inheritance could also include knowledge, like a hidden library full of rare magic books. This knowledge would make him a much more powerful wizard. And it might also lead to some interesting relationships. For instance, he could be related to some powerful wizarding families through his inheritance, which would change the way others in the wizarding world view him.
Obviously, Harry is the most important character. Then there might be his friends like Hermione and Ron. They could help him understand and manage his inheritance. There may also be some new characters, like an old wizard who is the keeper of the inheritance until Harry is ready. And of course, the antagonists like Draco Malfoy or any remaining Death Eaters might be interested in his inheritance, either to steal it or to stop Harry from using it to gain more power.
In fanfictions about Harry getting his creature inheritance, he may inherit from a magical creature like a dragon. This could endow him with incredible strength and the ability to breathe fire (in a more magical and less destructive way, perhaps). It could also make him more resistant to heat and fire - spells related to fire might not harm him as much. This new inheritance would likely change his relationships too. His friends might be in awe of his new powers, and his enemies would be more cautious around him.
In this fanfiction, Naruto might face various challenges while claiming his inheritance. It could involve dealing with hidden secrets about his family, perhaps some sort of special jutsu or a powerful item left behind. Maybe there are other characters who oppose his claim, leading to battles or political intrigue within the Hidden Leaf Village.
There could be new characters introduced as well. For example, an old wizard or witch who has knowledge about the specific creature inheritance Harry has. They could be a mentor figure, teaching Harry how to control and use his newfound abilities. And of course, the antagonists like Voldemort would be affected by Harry's new powers. They might try to find a way to counter or steal Harry's creature inheritance powers.
Another aspect could be related to his family heritage. Harry could inherit a special magical artifact that was passed down through the Potter family. This artifact might hold the key to some long - forgotten magic or a prophecy. As he explores his inheritance, he uncovers secrets about his family's past and its connection to the overall history of the wizarding world, which in turn helps him in his fight against Voldemort.
He might meet other wandering ninjas who are also on a quest for power or knowledge. They could either become his allies or foes depending on their motives.
Obviously, Naruto would be one of the main characters. There might also be his friends like Sasuke or Sakura. Maybe some of the older ninja like Kakashi or Iruka could also play important roles, as they might have knowledge about Naruto's inheritance or be involved in the process of him claiming it.
In this fanfiction, Naruto might use his inheritance to go on a journey of self - discovery. He could explore new jutsu or meet old foes with new power. Maybe he'll travel to places he's never been before to understand more about his family and his roots.
